Etymology: Platydoras: Greek, platys = flat + Greek, doras = skin (Ref. 45335).
More on author: Linnaeus.
Issue
Widespread and geographically variable species. Le Bail et al. (2000) recognized two distinct species of Platydoras in the Rio Maroni; however, their use of available names is questionable. Accurate determination of available names and the likely discovery of undescribed species await thorough revision.

Lives on the bottom and feeds on mollusks, crustaceans, and organic debris. Frequently occurs on sandy bottoms. Often escapes into the sediment where it hides among the anfractuosities of the submerged stocks (Ref. 35381). A juvenile in a stream of the rio Araguaia was recorded to clean the piscivorous characin Hoplias cf. malabaricus (Ref. 50806).
生活在底部並且吃軟體動物，甲殼動物與有機的殘礫。 時常生存於砂質底部。 經常逃入沉澱物在水面下的植物的彎曲的水道之中他躲在那裡中.(參考文獻 35381) 在 rio Araguaia 的一個水流的一個稚魚被記錄清理以魚為食的 characin Hoplias 比較 malabaricus 。 (參考文獻 50806)
